  1. 26. Paleomagnetic dating of a mysterious lake record from the Kerguelen archipelago by matching to paleomagnetic field models

    University essay from Lunds universitet/Geologiska institutionen

    Author : Kim Teilmann; [2016]
    Keywords : lake sediment; Kerguelen archipelago; paleomagnetic secular variation; paleomagnetism; paleomagnetic field models; slump deposits; Earth and Environmental Sciences;

    Abstract : Kerguelenöarna är en vulkanisk ögrupp belägen i det södra Indiska oceanen. Öarna ligger på polarfronten samt inom den cirkumpolära Antarktiska strömmen och södra halvklotets västvindsbälte. Detta gör Kerguelenöarna till en intressant plats för klimatstudier. READ MORE

  3. 27. Cambrian stratigraphy and depositional dynamics based on the Tomten-1 drill core, Falbygden, Västergötland, Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Frans Lundberg; [2016]
    Keywords : biostratigraphy; Sweden; Västergötland; drill core; agnostoids; trilobites; δ13 excursion DICE ; Cambrian; carbon isotope stratigraphy; Earth and Environmental Sciences;

    Abstract : The Tomten-1 drilling at Torbjörntorp in Västergötland, southern Sweden, penetrated 29.85 m of Cambrian Series 2 and 3, Furongian, and Lower and Middle Ordovician strata. The biostratigraphy, sedimentology and carbon isotope (δ[sup]13[/sup]C[sub]org[/sub]) stratigraphy of the core have been analysed. READ MORE

  4. 28. Lower to Middle Ordovician carbonate sedimentology and stratigraphy of the Pakri peninsula, north-western Estonia

    University essay from Lunds universitet/Geologiska institutionen

    Author : Niklas Brådenmark; [2016]
    Keywords : berggrundsgeologi; ordovicium; baltoskandiska grundhavet; havsnivå; kalksten; glaukonit hårdbottnar.; Earth and Environmental Sciences;

    Abstract : Sedimentologi och stratigrafi från senaste tidiga ordovicium till och med mellanordovicium i nordvästra Estland har undersökts. Studien omfattar klippsektioner och Testepere stenbrott på Pakrihalvön, samt en vägskärning utanför staden Tabasalu strax väster om Tallinn. READ MORE

  5. 29. Sedimentology and carbon isotope stratigraphy of Lower–Middle Ordovician successions of Slemmestad (Oslo-Asker, Norway) and Brunflo (Jämtland, Sweden)

    University essay from Lunds universitet/Geologiska institutionen

    Author : Olof Peterffy; [2015]
    Keywords : Ordovician; carbon isotope stratigraphy; Baltoscandia; MDICE; ’Blommiga bladet’; ’Blodläget’; Earth and Environmental Sciences;

    Abstract : Lower through Middle Ordovician strata are described with respect to sedimentology and carbon isotope stratigraphy from two areas, viz. two outcrops at Slemmestad in the Oslo-Asker district of southern Norway and a core section from the Brunflo area in Jämtland, central Sweden.

  6. 30. Environmental Controls on Snow Cover Thickness and Water Equivalent in Two Sub-Arctic Mountain Catchments

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Christopher Cosgrove; [2015]
    Keywords : Snow; hydrology; sub-Arctic; mountains; climate; landscape;

    Abstract : The spatial variability of snow cover characteristics (depth, density, and snow water equivalent [SWE]) has paramount importance for the management of water resources in mountain environments. Passive microwave (PM) inference of SWE from space-borne instrumentation is increasingly used but the reliability of this technique remains limited in mountainous areas. READ MORE
